TLV1117IKCS

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

TLV1117IKCS from Texas Instruments, in a TO-220-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ/GND bidirectional Adjust pin on the adjustable version (ADJ, which this TLV1117IKCS is) and ground pin on fixed-output versions; the datasheet lists its type as I/O and gives no other limit for this pin.
2 VOUT output Regulator output pin, rated for up to 800 mA output current; the adjustable version produces an output from 1.25 V to 13.8 V.
3 VIN power_in Regulator input pin; the recommended input range for the TLV1117 is 2.7 V to 15 V, and the absolute maximum continuous input voltage is 16 V.
